			          Atrial fibrillation (AF) causes an irregular heartbeat. There are various causes of AF. Medication can slow a fast heart rate and ease symptoms. Sometimes treatment can restore the heart rhythm back to normal. In addition, a medicine to prevent clots forming is usually advised to reduce the risk of having a stroke.

			          Atrial fibrillation (A-tre-al fi-bri-LA-shun), or AF, is the most common type of arrhythmia (ah-RITH-me-ah). An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.

			          Atrial Fibrillation (AFib)
			           
			          Atrial fibrillation (AFib) is an abnormal heart rhythm. The four chambers of the heart usually beat in a steady, rhythmic pattern. AFib means that the atria (upper chambers of the heart) are fibrillating or twitching quickly and creating an irregular rhythm.
